Fluid dispensing process

Abstract

An apparatus for the application of crease setting composition comprises at least one movable arm 12 capable of insertion into a leg of a pair of trousers to be creased, the arm carrying at, or near, one end thereof an applicator head 20 comprising a nozzle 22 for the application of crease setting composition and guide means 24 for locating the nozzle within the crease to be treated. Means are provided, for example, a pump or compressed air, for urging crease setting composition through the nozzle into the crease to be set in timed relationship with the relative movement between the applicator head 20 and the trousers 34. A method of operation is also disclosed.

I claim: 
     
       1. A process for the application of a crease setting composition for trousers having legs with crease lines thereon, comprising supporting said trousers on a conveyor, inserting into the leg of said trousers an apparatus capable of forcing outwardly the trouser leg at said crease and applying crease setting composition within said crease line at or near at least one of the points of said outward force, moving the trousers with respect to the apparatus while said outward force is maintained so as to deposit the crease setting composition in said crease line, removing said apparatus from said trouser legs, conveying the trousers to a subsequent work station, and repeating the process in a continuous manner. 
     
     
       2. A method as claimed in claim 1 in which the trousers are conveyed hanging down from a conveyor supported by the bottoms of the legs and are then lowered onto and moved upwardly from the apparatus before passing to the subsequent work station. 
     
     
       3. A method as claimed in claim 1 in which crease setting composition is pumped through the apparatus in timed relationship with the linear movement of the trousers so that a constant predetermined linear quantity of crease setting composition is deposited within the crease. 
     
     
       4. A process for applying a crease setting composition to a pair of trousers, which comprises: supporting said trousers on conveying means and moving said trousers to a work station; inserting into a leg of the trousers to be creased two arms, movable towards and away from one another, at least one of the arms carrying at or near one end thereof an applicator means for the application of crease setting composition; moving said arms away from one another so as to cause one of each arm to contact opposite creases of said trouser leg and guiding said applicator means within the crease to be treated; moving the trousers longitudinally with respect to said applicator means and urging crease setting composition therethrough into the crease in timed relationship with the relative movement between the applicator means and the trousers; moving the arms towards one another after sufficient crease setting composition has been applied; withdrawing the two movable arms from the pants leg, said movable arms being positioned towards one another to facilitate said inserting and withdrawing steps; and conveying the pants leg from said work station.
